Manual Operation Valves

Product Features: Our gate valves adopt advanced structural design, with excellent sealing performance, zero leakage and strong wear resistance. The valve core is made of high-quality materials (such as carbon steel, stainless steel, alloy steel), which can withstand high pressure, high temperature and corrosive media. The operation is flexible and labor-saving, and the opening and closing stroke is smooth, which can effectively avoid jamming. It has the advantages of simple structure, easy maintenance and long service life.


Application Scope: It is widely used in petroleum, chemical industry, natural gas, power plant, water treatment, municipal engineering, metallurgy, mining and other industries. It is suitable for on-off control of various media such as water, oil, gas, steam and corrosive liquids/gases, especially for large-diameter pipeline systems that require full-flow circulation.


Model Range: We provide a complete range of gate valve models, covering various standards such as ANSI, DIN, JIS, GB. The nominal diameter ranges from DN15 to DN2000, and the nominal pressure ranges from PN1.0 to PN100 (Class 150 to Class 600). Various connection methods are available, including flange connection, thread connection and welding connection, to meet different installation requirements.
